Has any had to replace knock sensor?s to regain max WOT Rpms. Iv went threw my intire fuel system and firing system. And all checks out fine. Only has 170H on 2000 5.7 Volvo 94-99 motor. No smoke no oil burn. But can only hit 4200 rpms WOT 3 people in boat 19 pitch prop. I?m thinking maybe the knock sensor is possible bad or both of them if there is 2 and retarding the timing. I run 89 octane. Thx.
